HTTP Error 502.5 - Process Failure

[laksh-parab]

I have asp.net core api and i have hosted this application in IIS. When i access api in broswer i see error in the browser

HTTP Error 502.5 - Process Failure

when i check event viewer, i see below error

Application 'MACHINE/WEBROOT/APPHOST/MySite' with physical root 'D:\MyFolder' failed to start process with commandline '"" ', ErrorCode = '0x80070057 : 0.

I am able to run my API in Kestrel using "dotnet api.dll" command at command prompt without any issue. So there is no issue with application startup.
On the production server; where this error is occurring; i have installed IIS 8.5, .Net Core 1.0.4 and Microsoft .Net Core 1.0.4 & 1.1.1 - Windows Server Hosting

I also have development server where i have installed IIS 8.5, .Net Core 1.0.1 and Windows Server Hosting 1.0.1. But on development server environment i am able to access API via IIS.

Since in production i can run application in Kestrel with .Net Core 1.0.4 i dont think its the issue with .net core version.
I am guessing its happening because of Microsoft .Net Core 1.0.4 & 1.1.1 - Windows Server Hosting. This version is different in development and production.

Here is my project.json and web.config
project.json
web.config

How do i fix this error?
Where would i find old versions of Windows Server Hosting installation files.?
I already looked at #256

dang it..it was my mistake. My IIS web site was pointing to C:\MyFolder instead of C:\MyFolder\Api
so closing issue
